Introduction, Specifications, and Pricing
We have tested the big unit, the Hydro G 1000W, recently, so we were due to take a look at the smaller of the units from FSP. FSP, as many are aware, may not be of the same popularity or notoriety as some of the more well-known brands such as Seasonic, EVGA, Corsair, and Thermaltake. However, FSP OEMs for many manufacturers, and you may not even know it.
The PSU we have today is an SFX unit, which means it's much smaller than standard ATX and is made for smaller form factor systems. SFX and SFX-L being much smaller mean that you obviously cannot fit nearly as many components, which means wattage availability will be limited. The technology has improved, and we have seen wattages grow north of 700W while offering efficiency rise up to platinum in some units.
Key features for the Dagger Pro SFX from FSP are listed as follows:
- Compliant with latest SFX12V V3.3
- Efficiency ≧ 90% at typical load
- MIA IC (Multiple Intelligence Ability) chip set inside
- Semi-fanless design for silent operation
- Quiet and long-lasting 92mm ball bearing fan
- All black ribbon cables
- Powerful single +12V rail design
- Full Japanese electrolytic capacitors
- Intel Latest CPU ready
- Full protections OCP, OVP, SCP, OPP, OTP
The MIA IC is a fascinating inclusion as it lists via FSP material as "An integrated power solution of FSP's own patented IC design with DC-DC module ensures solid power delivery to your system." This means that FSP developed its own controller to manage voltage regulation and means this supply should have top-notch power delivery. However, we must take marketing for what it is and place it under some real-world load to know what it can do.
The Dagger Pro we have today is the 650W model, which carries a part number of SDA2-650. There is also a 550W model for those who don't need the overhead available from the 650W model. The Dagger pro is Gold rated.
Here is the output table for the Dagger pro, and as you can see, it has a nominal rating of 54A on the +12V. This will be where our CPU and GPU will be pulling from primarily, while the lower rails will be used for various other components on the board and components.
Lastly, we take a look at the efficiency and noise charts supplied by FSP. The output chart shows over 90% efficiency at 20% - 50% load, which is what is considered a 'typical load.' Even at 115V AC input, such as here in the states, the efficiency never drops below 86% at the extreme top or bottom end, although I do not expect many to load a PSU to 100% simply because you are ensuring your system will fail.
The price for the Dagger Pro 650W shows up to the market at $114.99, which is quite a bit less than the comparable SilverStone 650W gold SFX unit at $144.99. Looking at SFX options in the 600 - 699W range, the next closest PSU in the stack would be the Thermaltake Toughpower SFX 600W Gold or the Corsair SF600, which is $139.99. It is, however, worth noting that the Corsair unit is platinum rated, which gives you a small bit more efficiency.
